The nutrient contents of peanuts (Arachis hypogaea L.) grown under nutrient-sufficient conditions were determined in relation to yields of lines derived from 15 cultivars. Four plant portions of the lines, each a single seed selection, representing four market types were analyzed for contents of eight nutrients. In general, the fruit was highest in P and Zn contents and lowest of the four portions in K, Ca, Mg, B, Mn, and Cu contents. The upper central stem leaves were highest in Ca, Mg, Mn, and B contents and intermediate in P, K, Zn, and Cu contents. The first lateral branch leaves were highest in K content, intermediate in P, Ca, Mg, B, and Cu contents and lower in Zn content than the above portions. Copper content was highest and P content lowest in the hypocotyl whereas the other nutrient contents in this portion were generally higher than in the fruit portion only. Lines of the large-seeded Virginia type were generally highest in K, Ca, and B contents, intermediate in Mg content, and lowest in P content of the four types. The small-seeded Virginia type lines were highest in Mg content, equivalent in Cu and Mn content to the large-seeded lines, and intermediate in P and K contents. The Spanish and Valencia lines were highest in P content, lowest in Cu content, but equivalent to the small-seeded Virginia lines in K, Ca, B and Mn contents.
